Wurf/gm u rcientor desirednnumber of bottles have been placed in the tank 1 inthe manner described, the valve 19 is opened, as is als the valve 2l and Water admitted through. tiie spray pipe 7 to the interior of the tank, the spray thus produced being throvynonfto and running l do'wn the sides of Aeachbottle. After admitting the water' valve 25 is opened andsteam jetted into the 'spray pipe, 'With'theeii'ect to eradually heat the Water and deliver it to t. e bottlesin increasing degrees of heat. 'When suilcient Water has accumulated in the bottom of the tank, sufiieient for ex-` ample to cover the heating pipe 9, the Valve 19 is' closed and the valve 20 is opened, the -valyes 27 and 32 being also opened, The

' opened, so that'the `Water romr'the main tank is pumped. intothe heated 'Water stor age tan. ,12. lg-iter the heated Wuaterhas been pnmped'rom the tank l, the valve 15 is Iclosed and the 'pump stopped. Valves 19 i l are then opened and Water admitted directly from the main source tif-supply to the tank to cool the bottle. As the Water thus admitted passes through the spraypipe 7, it is obvious that owing to the heated condition oi. said pipe, the Water will be ini tially heated and gradually cooled, thereby properly cooling the bottles without the liability of breaking them. After a suiii cient quantity of AWater has been admitted to the main tank for circulating purposes, the supply is shut oil 1oy closing the valve i9, and the valves 2l and 32 being then open and the pump started, the cold Water f is circulated exactly as described in connection with the heated Water until the proper cooling of the milk is had. yThe vcold Water, after its use in the main tank is drawn into the cold water storage tank, from which after subsequent use, it is 'taken by the pump being maintained at the desired degree of low temperature in the cold Water storage tank by a ysuitable means for cooling.

itis preferred that in the apparatus each bottle be supplied with a metal cap' or other means of protecting the usual paper disk stopper, so as 'to prevent softening of the latter or any liability of contaminating the contents of the bottle.

By reason of the conservation of the heating and chilling mediums, there is a material saving in time owing tothe less time required in bringing?, such mediums to their desired high and oW" temperatures, and by during its circulatory innfemeny minus reason of such economy of time the appac5 ratus is more eective as it permits practically a A continuous pasteurizing action.

What-is claimed is;

1. A pasteurizing apparatus including a tank, a spray pipe arranged in the upper portion thereof, means for circulating'water taken from bottom of tank up' through the spray ipe, a-heating pipe in theulower portion o the tank adapted tobe submerged by a head of Water therein, and a steam 4'i supply in communication with the spray pipe .and the heating pipe,whereby bo the' ingoing and outgoing water is kheated during its circulatory movement.

2. A. pasteurizing apparatus including .a v main tank, a hot Waterstorage-tank, a cold Water storage tank, a' punl'p, independent means of circulation between the pump and main tank, independent means of circ`u1e. tion betweenthe pump and hot water stor-4 85 age tank, and a communication between, the pump .and main tankthrugh thecold wateraeteregQ-ill?, .f
